The ‘triplen’ harmonics i.e. the 3rd, 9th and the 15th harmonics of the line frequency cause more damage to the system and heat up the neutral. Why is that? This is because these harmonics are actually ‘additive’ (vector addition) in nature in the neutral of a 3 phase ‘wye’ circuit. This is easy to understand. In a 3 phase ‘wye’...
The term harmonics for decades has been a terminology or a buzz word, making many people reconsider the effectiveness of their building’s wiring system. But over the years, it has shaped new meanings. The presence of harmonics in electrical systems means that the current and voltage are distorted and deviate from sinusoidal waveforms. Harmonics have short and long-term effects on...
